Problems solved by technology

This situation prevents the existing two-way opening and closing door leaf from being applied to the field of fire door technology. Even if it is used as a fire door leaf, the sealing effect cannot be guaranteed.
[0006] At present, there is no steel fire door on the market that can open in both directions, which can not only ensure the safety of tunnel driving, but also ensure sufficient evacuation capacity, and of course there is no flat-opening double-leaf two-way opening and closing steel fire door that can ensure the sealing effect at the same time

Embodiment 1

[0046] Such as Figure 1 to Figure 10 As shown, the side-opening double-leaf two-way opening and closing steel fire door of the present invention includes a steel door frame 1 and a steel door leaf. When in use, the steel door frame 1 is fixedly connected to the tunnel wall 4 and forms the outer boundary of the fire door. The door leaves include a first door leaf 2 and a second door leaf 3, and the first door leaf 2 and the second door leaf 3 are rotatably connected to the door frame 1 through a steel sleeve hinge structure. Both sides of the first door leaf 2 and the second door leaf 3 are provided with handles 5 .

[0047] Such as Figure 1 to Figure 4 As shown, the steel sleeve hinge structure includes a steel frame sleeve hinge sleeve 6 fixedly connected to the door frame 1, a steel fan sleeve hinge sleeve 7 fixedly connected to the door leaf, and a hinge sleeve installed on the frame sleeve. Cover 6 and the steel sleeve shaft hinge core 8 in the fan cover shaft hinge sl...

Embodiment 2

[0067] The difference between this embodiment and Embodiment 1 is that the manufacturing method of the flat-opening double-leaf two-way opening and closing steel fire door is different, and the manufacturing method of this embodiment is carried out in the following steps:

[0068] 1. Make a steel door frame 1 with bumper posts 16 on the upper beam, and fix the door frame 1 with the tunnel wall 4;

[0069] 2. Make the frame sleeve shaft hinge sleeve 6, the fan sleeve shaft hinge sleeve 7 and the sleeve shaft hinge core 8, and put the frame sleeve shaft rubber sleeve and the fan sleeve shaft hinge sleeve 7 on the sleeve shaft hinge core 8 alternately;

[0070] 3. Fix the upper and lower ends of the shaft hinge core 8 on the door frame 1, and connect the frame sleeve shaft hinge sleeve 6 with the door frame 1;

[0071] 4. Make the door leaf, including the first door leaf 2 and the second door leaf 3, make steel column grooves on the upper end faces of the first door leaf 2 and th...

Abstract

The invention discloses a side-opening double-leaf two-way opening and closing steel fireproof door and a manufacturing method thereof. The fireproof door comprises a steel doorframe and steel door leaves. When the door is used, the steel doorframe is fixedly connected to the wall of a tunnel and forms the external boundary of the fireproof door. The door leaves include a first door leaf and a second door leaf which are connected to the doorframe through a steel sleeve hinge structure in a rotary manner; the steel sleeve hinge structure comprises a steel frame sleeve hinge sleeve fixedly connected to the doorframe, a steel leaf sleeve hinge sleeve fixedly connected to the door leaves and a steel sleeve hinge cylinder which penetrates through the frame sleeve hinge sleeve and the leaf sleeve hinge sleeve; and two ends of the sleeve hinge cylinder are fixedly connected to the doorframe. The fireproof door not only ensures driving safety in the tunnel but also ensures enough evacuation capability. The doorframe and the door leaves are connected with each other in a rotary manner through the sleeve hinge structure, and through the sleeve hinge structure, the requirements of side opening and opening and closing in two ways are reached; when the door leaves rotate around the sleeve hinge cylinder, the rotation angle is bigger than or equal to 180 degrees; and in such way, the evacuation requirement in the bidirectional tunnel can be satisfied.

Description

technical field [0001] The invention relates to a flat-opening double-leaf two-way opening and closing steel fireproof door used in a two-way tunnel. Background technique [0002] With the development of human social civilization, people have built various buildings and structures, and developed various fire protection technologies accordingly. Fire doors are one of the fire protection technologies. A fire door is a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. According to the opening method, fire doors can be divided into flat opening, sliding, rolling shutter and so on. According to the number of doors, it can generally be divided into single-leaf, double-leaf and multi-leaf doors. Among them, the side-opening single-leaf and double-leaf doors are simple and convenient to operate, and are widely used. The side-opening fire door is composed of a door frame, a door leaf, fireproof hinge...
